      "每月定期将所有开发人员的代码合并一次并进行测试。",
      "使用 Jenkins 工具来替代 Git 作为版本控制系统。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "持续集成（CI）的核心思想是频繁地集成代码。文档明确指出，CI 实践是指“只要代码有变更，就自动运行构建和测试，反馈运行结果”，并且“强调开发人员提交了新代码之后，立刻进行构建、（单元）测试”。",
    "source": "文档中「2.1 持续集成（Continuous Integration)」部分",
    "hint": "回顾一下CI的目标，它强调的是“立刻”和“自动”这两个关键词。"

    "question": "文档如何区分“持续交付（Continuous Delivery）”和“持续部署（Continuous Deployment）”？",
    "options": [
      "持续交付是持续部署的基础，侧重于编译和打包。",
      "二者没有本质区别，只是叫法不同。",
      "持续交付将代码部署到类生产环境并可手动发布，而持续部署则将通过测试的代码自动发布到生产环境。",
      "持续交付是手动的，持续部署是自动的。"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档中对这两个概念有清晰的界定。持续交付（Continuous Delivery）是将集成后的代码部署到类生产环境，并可以“手动部署到生产环境”。而持续部署（Continuous Deployment）则更进一步，是“在持续交付的基础上，由机器自动完成部署”。这个关键区别在于最后一步到生产环境是手动还是自动。",
    "source": "文档中「2.2 持续交付（Continuous Delivery）」和「2.3 持续部署（Continuous Deployment）」部分",
    "hint": "注意文档中关于“手动部署”和“由机器自动完成部署”的描述，这是区分二者的关键点。"
  },
  {
    "question": "在CI/CD流程中，“部署（Deployment）”和“发布（Release）”的主要区别是什么？",
    "options": [
      "部署是将代码打包成war或jar包，发布是启动应用服务器。",
      "部署是技术行为，指代码或配置变更在生产环境生效；发布是业务行为，指功能变化对最终用户可见。",
      "部署是开发人员的工作，发布是测试人员的工作。",
      "部署和发布是同义词，都指将应用更新到服务器。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档对这两个关键词有明确的定义。部署（Deployment）指的是“应用组件或基本设施的代码或配置变更在产品环境生效”，这是一个技术层面的动作。而发布（Release）则强调“具有业务影响的功能变化对最终用户可见”，这是一个业务层面的结果。一个系统可以频繁部署，但只在特定时机进行发布。",
    "source": "文档中「2.4 持续集成中关键词解释」部分",
    "hint": "思考一下：代码上线了，但用户还看不到新功能（比如通过灰度开关控制），这个过程属于部署还是发布？"

      "作为自动化调度中心，负责从Git拉取代码、编译打包，并远程部署到应用服务器。",
      "作为数据库服务器，存储应用程序的业务数据。"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档的“部署流程”章节详细描述了Jenkins的工作：1. 从Git拉取代码；2. 使用Maven编译打包；3. 连接应用服务器并传送文件；4. 在应用服务器上执行启动脚本。这表明Jenkins是一个核心的自动化调度和执行者，它连接了代码仓库和应用服务器。",
    "source": "文档中「5. 部署流程」和「Jenkins是什么」部分",
    "hint": "回想一下部署流程图，Jenkins位于哪个位置，连接了哪些系统？"

      "Maven Integration plugin",
      "Deploy to container",
      "InitialAdminPassword Plugin"
    ],
    "correctAnswerIndex": 2,
    "explanation": "在“配置项目远程发布”一节中，文档明确指出，如果配置界面没有 'Deploy war/ear to a container' 选项，就需要去安装 'Deploy to container' 插件。这个插件专门负责将构建产物（如WAR文件）部署到指定的应用容器（如Tomcat）中。",
    "source": "文档中「11.4 配置项目远程发布」部分",
    "hint": "文档中有一句提示：“如果这里没有 ‘Deploy war/ear to a container’选项 ，说明没有安装...插件”。"

    "question": "为了实现代码推送到Gitee后自动触发Jenkins构建，需要进行什么关键配置？",

      "在Jenkins中设置一个定时任务，每分钟检查一次Gitee仓库。",
      "在Gitee仓库的WebHooks设置中，添加Jenkins提供的构建URL。",
      "开发人员每次推送代码后，需要手动登录Jenkins点击“立即构建”。",
      "修改Jenkins的全局安全配置，允许匿名用户执行任何操作。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档在“配置自动构建”章节中详细演示了如何实现自动化触发。核心步骤是在Gitee项目的“WebHooks”管理页面，将Jenkins任务中提供的特定URL（构建触发器URL）添加进去。这样，每当Gitee接收到代码推送事件，就会自动向该URL发送一个HTTP请求，从而触发Jenkins的构建任务。",
    "source": "文档中「12.2 把自动构建地址配置到Gitee的WebHooks上」部分",
    "hint": "文档中有一个将Jenkins的URL配置到Gitee页面的截图，这个功能叫什么？"

    "question": "根据文档「3.持续集成优点」，以下哪一项不属于持续集成带来的好处？",
    "options": [
      "能够快速暴露和定位错误。",
      "降低因大量代码一次性集成而带来的风险。",
      "完全消除所有软件缺陷和逻辑漏洞。",
      "保证开发团队提交的代码具有较高的质量。"
    ],
    "correctAnswerIndex": 2,
    "explanation": "持续集成是一种优秀的工程实践，它可以“快速暴露错误”、“定位错误更容易”、“降低整体集成风险”，从而提升代码质量和迭代速度。但是，它不能保证软件是100%无缺陷的。业务逻辑错误、设计缺陷等问题依然可能存在，CI/CD流程能帮助尽早发现问题，但无法消除所有问题。",
